I've lodged issues.scala-lang.org/browse/SI-9188 to track this.

comment Implicit parameters break type inference or inference does not suffice for their resolution?
Here is a comparison of the typechecking internals for the program with and without the implicit parameter: rawgit.com/retronym/22260bca2087f21cfd41/raw/out.html Without an implicit parameter, the undetermined type variable O is inferred as Nothing in order to adapt the result type of execute to the declared typed Int. With the implicit parameter, the implicit search for Ord[O] cannot resolves a unique matching implicit, and typechecking fails before considering Int.

comment Why do I need jsr305 to use guava in scala?
Scala 2.11.1 and above now handle the missing annotations gracefully; you no longer need jsr305 on the classpath.

comment presentation compiler: type completion in method call with more than one argument
If you can express the issue with a failing test case of the presentation compiler, I can take a look. Just follow the pattern from my commit above and run ant build; ./test/partest --update-check test/files/presentation/my-test-case to run the test and produce a check file with the completion list. More docs about writing presentation compiler tests: github.com/scala/scala/blob/2.11.x/src/interactive/scala/tools/…

What version of Scala are you using? I just tested this with 2.11, and both variants offer completions: github.com/retronym/scala/compare/scala:2.11.x...topic/…

comment Hidden performance cost in Scala?
Great answer. Would be even greater if you added the bytecode listings of the two methods!
